Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.

I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.

Dear customer, the main code is the first one that tells us about a pressure problem in the injection rail monitoring, it is precisely speaking that during the start of the engine.

I'm telling you this because the second error code referring to the catalyst system can be rooted to the fuel pressure problem.

The oxygen sensor is a sensor found near the catalyst. What this sensor does is measure the amount of combustible air that is burned in the engine through a reading of the exhaust gases.

What is happening is that the mixture is not stoichiometric, i.e there is not the same amount of air with the same amount of fuel, therefore the vehicle tells you that the cat is receiving a high or low signal.

In general, fuel pressure problems are due to lack of maintenance in the injection system, such as lack offuel filter replacement, lack of injectors cleaning, including the pump, due to having some kind of problems, so it is advisable to start with simple servicing the vehicle and removing the injectors t clean them and checking the fuel pump pressure.

Do you understand me, dear customer?
Please let me know if you have any doubt or if there is anything else i can help you with.
Kind regards, Sebastian.

It is my pleasure can help!

Dear customer, what happens is that this is another area of failure. The steering column systems can work erroneously and cause this kind of error code due to various factors.

I would recommend you proceed directly to replace the switch, but you first have to check several aspects before not making the mistake of spending money unnecessarily.

What I would recommend is that you verify all these parameters with the diagnostic equipment through the live data stream, in this way you will not waste time or money because the advantage is that these vehicles throw all the electronic operation through the equipment diagnostic.
